@nitalisa It's good you have a mental health therapist you can talk with.

I'd like to suggest that one should work their physician on mental health medications and ask how supplements interact with these.

Perhaps your therapist suggested a trial of medication with L-tryptophan? It is out of the scope of practice for a mental health therapist to even suggest a specific medication. They do not have the training or license to do that. Doctoral level psychologists can prescribe medications in specific states within the US but only with additional training.
